[Field of Industrial Application] The present invention relates to a tundish for horizontal continuous casting, and a method for discharging the remaining molten metal in the tundish after the completion of horizontal continuous casting. [Prior Art] In horizontal continuous casting, a mold is provided in the horizontal direction at the lower part of the side wall of a tundish, and a slab is pulled out in the horizontal direction by the mold and continuously cast.
The mold and the tundish are directly connected through a feed nozzle. FIG. 4 is a sectional view showing a conventional horizontal continuous casting tundish. 1
is a tundish, 2 is a molten metal, 3 is a feed nozzle, 4 is a mold, 5 is an extrapolation type plug, 6 is a nozzle for discharging residual metal, 7 is solidified metal, 8 is a flow of molten metal, 9 is a side wall of a tundish, 10 is the bottom of the tundish. The molten metal 2 is held in the tundish 1 and flows into the mold 4 through the feed nozzle 3. When the surface of the molten metal 2 falls below the upper surface of the mold 4 at the end of casting, a void is created on the upper surface of the mold 4. If these voids occur, the mold 4 will not be filled with molten metal, making it impossible to maintain a regular billet shape. In order to avoid this, the remaining molten metal 2 in the tundish 1 is removed from the residual metal discharge nozzle 6 by pulling out the external plug 5 inserted into the residual metal discharge nozzle 6 at the bottom of the tundish 1.
It was leaking from. [Problems to be solved by the invention] However, there is a molten metal 2 in this tundish 1.
During casting, the flow 8 of molten metal flows in the direction of the feed nozzle 3 in the tundish 1, so the temperature of the side wall 9 and the bottom 10 of the side wall 9 facing the feed nozzle 3 inside the tundish 1 decreases, and a base metal 7 in which the molten metal solidifies and solidifies is generated. However, there were problems in that the molten metal did not flow out even when the external plug 5 was removed, and the external plug 5 broke and did not come out properly. This invention was made in view of the above circumstances, and is designed so that the area around the external plug does not solidify and stick, and when the external plug is removed, the molten metal flows out immediately from the residual metal discharge nozzle. The purpose is to [Means for Solving the Problems] The horizontal continuous casting tundish according to the present invention includes a feed nozzle at the bottom of one side wall of the tundish for supplying molten metal to a horizontal mold;
A residual metal discharge nozzle and an external plug inserted into the residual metal discharge nozzle are provided at the lower part of the other side wall, and an opening through which molten metal flows is provided between the feed nozzle and the residual metal discharge nozzle. A runner having a runner is connected thereto, and the opening of the runner is provided near the remaining hot water discharge nozzle. [Operation] Since this invention is configured as described above,
The molten metal flows in from a position near the molten metal discharge nozzle, and this area is always kept at a high temperature, so there is no solidified solidified metal, and the extraction of the external plug can be done smoothly. . [Embodiment] An embodiment of the present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 is a sectional view of an embodiment of a tundish for horizontal continuous casting according to the present invention. FIG. 2 is a sectional view taken along line XX' in FIG. FIG. 3 is a plan view of FIG. 1. 11 is an opening into which the molten metal flows; 12
is a runner having an opening. Reference symbols in other drawings are the same as those described in the prior art. The runner 12 having an opening is made of refractory material, and the inside thereof is circular and hollow. One end of the runner pipe 12 having the opening is bonded to the feed nozzle 3, and the other end is bonded to the residual hot water discharge nozzle 6. The opening 11 into which the molten metal flows is the runner pipe 1
2 and near the remaining hot water discharge nozzle 69. Next, the operation of this embodiment will be explained. Before receiving the molten metal 2, the inside of the tundish 1 is preheated with fuel (1200 to 1300°C), and then the molten metal 2 is poured from a ladle (not shown) toward the bottom 10 of the tundish 1. The molten metal 2 injected into the tundish 1 flows into the runner 12 (for example, 130 mmΦ) through the opening 11 (for example, 100 mmΦ), and the runner 12 is filled with the molten metal 2, and the side wall 9 reaches a certain height (for example, 500 mmh), a pull-out device (not shown) inserted into the mold 4 is activated to pull out the slab from the mold 4. Then, water pipe 1
As the molten steel 2 moves into the mold 4, the molten steel 2 in the tundish 1 flows into the runner pipe 12 through the opening 11. Since the high-temperature molten metal 2 always flows in the vicinity of the residual metal discharge nozzle 6 in the flow 8 of the molten metal, the base metal 7 in which the molten metal 2 is solidified and fixed is not generated. Therefore, when the level of the molten metal 2 reaches the upper end of the runner pipe 12 at the end of casting, when the external plug 5 of the residual metal discharge nozzle 6 is pulled out, the molten metal immediately flows out. Table 1 shows the open area ratio of the base metal 7 attached to the 5 parts of the extrapolation type plug according to the conventional method and the embodiment of the present invention.
As is clear from this table, the porosity was 100% in the examples of the present invention.
